The goal of this project is the development of an angular application which allows pilots to analyze flight data recordings made using EFIS instruments. Currently the G1000 will be supported.

EFISP will allow the user to plot barometric altitude, indicated airspeed, power settings and more.

The flight itself will be shown on a map which will be segmented by either cruise, climb or descent segments where cruise segments display the mean altitude and climb as well as descend segments show the mean climb/descend rate.

Altitudes are segmented using the rolling mean of the barometric climb rate.

A prototype has been created using a python leaflet.js API.

Segmentation in the prototype is performed by applying a rolling mean with a 60 second window on the barometric vertical speed.

For each time step the current state is saved where cruise is the initial state.

If the current state is cruise and a change of more than 250ft/m is detected the current state will be changed to either climb or descend, based upon the sign of the climb rate. The TOD or BOC will be set at the last point in time where the vertical speed was still below the zero detection limit \epsilon_0 of 5 ft/m.

If the current state is not cruise and the vertical speed falls below the zero detection limit of 5 ft/m the state will be changed to cruise and a BOD or TOC will be set at the point 60s before the detection.
